Abstract
Embodiments of the invention are directed to a method of controlling a mover device The method includes generating a moving force from a moving force generating unit to move a processing base with respect to a movable base, thereby moving the processing base with respect to a fixed base as a result of the movement of the processing base with respect to the movable base; moving the movable base on the fixed base in the opposite direction to the moving direction of the processing base by virtue of a reaction force caused by the moving force generated from the moving force generating unit to move the processing base, so that the movable base moves in the opposite direction to the moving direction of the processing base on the fixed base. The method further includes controlling the moving velocity of the processing base with respect to the fixed base.
